IoT Penetration Testing Cookbook

By: Aaron Guzman, Aditya Gupta

Overview of this book

IoT is an upcoming trend in the IT industry today; there are a lot of IoT devices on the market, but there is a minimal understanding of how to safeguard them. If you are a security enthusiast or pentester, this book will help you understand how to exploit and secure IoT devices. This book follows a recipe-based approach, giving you practical experience in securing upcoming smart devices. It starts with practical recipes on how to analyze IoT device architectures and identify vulnerabilities. Then, it focuses on enhancing your pentesting skill set, teaching you how to exploit a vulnerable IoT device, along with identifying vulnerabilities in IoT device firmware. Next, this book teaches you how to secure embedded devices and exploit smart devices with hardware techniques. Moving forward, this book reveals advanced hardware pentesting techniques, along with software-defined, radio-based IoT pentesting with Zigbee and Z-Wave. Finally, this book also covers how to use new and unique pentesting techniques for different IoT devices, along with smart devices connected to the cloud. By the end of this book, you will have a fair understanding of how to use different pentesting techniques to exploit and secure various IoT devices.

Threat modeling of an IoT web application

Continuing our threat modeling exercises for our DVR, we will work on breaking down its web applications. Our DVR contains two types of web applications. One web application is embedded, running off of the DVR itself. The second web application is a SaaS application provided by the vendor for remote access to the DVR and its camera feeds.

The SaaS application accesses the embedded DVR within the LAN. We have a better sense of what runs on the embedded web application locally on the DVR rather than the vendor SaaS application. Earlier in the chapter, we did mention some technologies utilized for the vendor web application but no additional information is known at this time. We will start by drawing out the architecture of the embedded web application and touch on the vendor SaaS application in the threats section rather than drawing its unknown architecture.

How to do it...

At this point, we should have a good idea of how to conduct threat models from...
